Definitions
- connection means may facilitate the connection, disconnection, or maintenance of components of the system including the replacement of the collection canister.
- the connection means permits the collection canister to be released for emptying or disposal during a course of therapy.
- the collection canister collects exudates from the wound bed which has been removed under subatmospheric pressure supplied by the control unit. When full, the collection canister is removed and replaced with a new canister which is also connectable through connection means with the housing of the control unit.
- the control unit may be intended for reuse.
- FIG. 2A is a perspective view of the subatmospheric pressure mechanism illustrating the control unit housing, collection canister and a latch coupling for releasably connecting the collection canister to the control unit housing;
- FIG. 2C is a perspective view of another embodiment of a latch coupling mechanism for releasably connecting the control unit housing and the collection canister;
- a non-adherent material may be selected such that contact member 108 does not tend to cling to wound bed “w” or surrounding material when it is removed.
- Exemplary materials that may be used as a contact member 108 are sold under the trademarks CURITY® Non-Adherent Dressing or XEROFLO® by Tyco Healthcare Group, LP (d/b/a Covidien)
- Outer member or wound covering 112 encompasses the perimeter of the wound dressing 102 to surround wound bed “w” and to provide a liquid-tight seal around the perimeter “p” of the wound bed “w.”
- the sealing mechanism may be any biocompatible adhesive bonded to the perimeter of wound covering 112 .
- wound covering 112 may act as both a microbial barrier and a fluid barrier to prevent contaminants from entering wound bed “w” and for maintaining the integrity thereof.
- Conduit 106 extends from subatmospheric pressure mechanism 104 to provide fluid communication between the interior of the wound dressing 102 and subatmospheric pressure mechanism 104 .
- Any suitable conduit may be used including those fabricated from flexible elastomeric or polymeric materials.
- Conduit 106 may connect to subatmospheric pressure mechanism 104 or other system components by conventional air tight means such as friction fit, bayonet coupling, or barbed connectors.
- the conduit connections may be made permanent, or alternatively a quick-disconnect or other releasable means may be used to provide some adjustment flexibility to the apparatus.
- Fluid conduit 106 may comprise the same material of construction along the entire length of the tubing or may assume an alternate form, e.g., it may include several distinct tubes connected to each other through conventional means.
- the control circuitry recognizes changes in state of switch 829 and activates or de-activates the magnetic field of electromagnet 831 by altering the flow of current from a power source 168 (not shown).
- the magnetic field of electromagnet 831 can be manipulated over a wide range by controlling the amount of electric current from the power source.
